Detailed Description

The QtxIntSpinBox class represents the widget for entering the integer values. In addition to the functionality provided by QSpinBox, this class supports "cleared" state - this is the state corresponding to "None" (or empty) entered value.

To set "cleared" state use setCleared() method. To check if the spin box stores "cleared" state, use isCleared() method. For example:

if (mySpinBox->isCleared()) {
  ... // process "None" state
}
else {
  int value = mySpinBox->value();
  ... // process entered value
}

Constructor & Destructor Documentation

QtxIntSpinBox::QtxIntSpinBox

(

QWidget *

parent = 0

)

Constructs a spin box with 0 as minimum value and 99 as maximum value, a step value of 1. The value is initially set to 0.

Parameters

parent

parent object

References onTextChanged().

QtxIntSpinBox::QtxIntSpinBox	(	int	min,
		int	max,
		int	step = 1,
		QWidget *	parent = 0
	)

Constructs a spin box with specified minimum, maximum and step value. The value is initially set to the minimum value.

Parameters

min	spin box minimum possible value
max	spin box maximum possible value
step	spin box increment/decrement value
parent	parent object

const

Returns

true if spin box is cleared

Parameters

txt	current spin box text (not used)

References myCleared.

void QtxIntSpinBox::setCleared ( const bool  on )

virtual

Parameters

on	new "cleared" status

References myCleared.

void QtxIntSpinBox::stepBy ( int  steps )

virtual

The steps value can be any integer number. If it is > 0, the value incrementing is done, otherwise value is decremented steps times.

Parameters

steps

number of increment/decrement steps

Reimplemented in SalomeApp_IntSpinBox.

QString QtxIntSpinBox::textFromValue ( int  val ) const

protectedvirtual

Parameters

val	value being converted

Returns

string containing the converted value

Reimplemented in SalomeApp_IntSpinBox.
